Roentgen appearance of the excluded colon after colostomy for infantile Hirschsprung's disease.

Abstract

Following colostomy and abdominoperineal pull-through procedures for Hirschsprung’s disease, the colon distal to the colostomy presents a striking roentgen appearance of nondistensibility, and thickness and nodularity of the mucosal relief.These findings correlated well with the grossly nodular mucosa noted on gross inspection of the colon at surgery, and histologic sections of the resected colon.The changes are probably a combination of mucosal redundancy caused by contraction of hypertrophic muscle and lymphoid tissue proliferation related to nonspecific factors, such as infections and possibly disuse.
